2.15 Enhanced Functions For Digital Standard 3GPP W-CDMA (FDD)
Option SMIQB48 expands the scope of functions of option SMIQB45 and offers the following features:
• Sequences with a length of up to 2044 frames (SMIQB45: 13 frames)
• Data lists for data fields and TPC
• External control of channel power in real time
• Channel coding
• Insertion of bit errors (for testing a BER tester)
• Insertion of block errors (for testing a BLER tester
• Simulation of orthogonal channel noise (OCNS)
• Simulation of up to 64 additional mobile stations
• Simulation of a channel-coded P-CCPCH (BCP) with system frame number
2.15.1 Test Setup
Fig. 2-163 Complete setup for testing a W-CDMA receiver with the SMIQ
This block shows the different functional blocks of the SMIQ with built-in option SMIQB48.
Blocks "Long Sequences/Channel Coding", "Bit/Block Error Insertion", "OCNS" and "External Power
Control" are part of option SMIQB48 and will be described in detail.
"Noise" is available only if option SMIQB17 is built-in. For a description see section " Noise Generator
and Distortion Simulator".
To simulate "Fading", option SMIQB14/SMIQB15 or SMIQB49 is required. This option is described in
the section on "Fading Simulation".
